Can I use a Spyder2 with my Projectore and PS3, Cable box, HTPC and upscaling DVD

HCFR with the Spyder2 can be used to calibrate your display without a HTPC involved. You do need a PC to run HCFR and plug the Spyder2 into it. Additionally, you need some manner to display specific test patterns (usually using a DVD) to accomplish the calibration.

If you happen to have a HTPC - it allows you to make use of HCFR on that PC, and HCFR has built in patterns eliminating the need for a pattern source (DVD).

You'll have trouble getting patterns from your cable box.

Additionally, as you use your receiver to feed the single HDMI - you'll need to make adjustments at your sources to make them as similar as possible.

I strongly suggest you read, and read, and read this forum for more details before you leap into a purchase.

The Spyder2 is widely commented as being less accurate than some of the other low cost devices (under $150). However, there is a point of diminishing returns. Human vision is extremely forgiving, and small variations in accuracy are nearly impossible to spot.

None of the low cost sensors will give you a "perfectly calibrated" zero deltaE deviation image (it is reasonable to expect to be within 3 deltaE IMHO). Most, if not all, of them will not give useful readings below 30IRE.

My experience - as a non-professional - has been that the sensor based calibration has helped me do a better job than I could have ever done by eye. The resulting image has been pleasing, but did take some getting used to. I've had a lot of fun learning about the technology.

My approach is - use the sensor to tweak. Verify results by eye. Iterate until I'm happy with both the sensor readings, and how it looks.
